HER2 Status by Standardized Immunohistochemistry and Silver-Enhanced In Situ Hybridization in Korean Breast Cancer
PURPOSE Amplification of the human epidermal growth factor receptor 2 (HER2) gene occurs in 18% to 20% of breast cancers, and it is recognized as a prognostic and predictive marker. We investigated the HER2 status in Korean breast cancer by immunohistochemistry (IHC) and silver-enhanced in situ hybridization (SISH), as the first step toward building a nationwide quality assurance program for HE...
متن کاملDual-color Silver Enhanced in situ Hybridization for Determining HER2
Amplification of the HER2/neu gene in 18-20% of patients with breast cancer produces the primary mechanism of HER2 protein overexpression (PenaultLlorca et al., 2009; Thang et al., 2011; Dekker et al., 2012). The HER2 gene is a tumor marker associated with rapid tumor growth, increased recurrence rate after surgery, and decreased life expectancy (Penault-Llorca et al., 2009; Thang et al., 2011)...
متن کاملEvaluation of Immunohistochemistry-Equivocal (2+) HER2 Gene Status in Invasive Breast Cancer by Silver DNA in Situ Hybridization (SISH) and its Association with Clinicopathological Variables
Background and Objective:Determination of HER2 gene is crucial in breast carcinoma management and prognosis, as HER2 alterations are linked to a shorter disease-free period, overall survival and resistance to tamoxifen anti-estrogen therapy and other chemotherapy regimens, regardless of the nodal or hormone receptor status. This study aimed to...
متن کاملChromogenic in situ Hybridization Compared with Real Time Quantitative Polymerase Chain Reaction to Evaluate HER2/neu Status in Breast Cancer
Background and objective: The assessment of human epidermal growth factor receptor 2 (HER2) status has become of great importance in the diagnosis of breast cancer. The aim of this study was to investigate the diagnostic value of quantitative Polymerase Chain Reaction (qPCR) and Chromogenic In Situ Hybridization (CISH) to assess HER2 status of biopsy specimens. <...
متن کاملSilver-Enhanced In Situ Hybridization as an Alternative to Fluorescence In Situ Hybridization for Assaying HER2 Amplification in Clinical Breast Cancer
PURPOSE Valid determination of HER2 status is a prerequisite to establish an adequate treatment strategy for breast cancer patients, regardless of the disease stage. The goal of this study was to examine the feasibility of the newly developed silver-enhanced in situ hybridization (SISH) technique as an alternative to fluorescence in situ hybridization (FISH) for HER2 assay in primary invasive b...
